What is the need for adding crystalline_materials to path while compiling?

[Quantumstud]

In the readme file, it has been mentioned that while compiling we have to add the 'crystalline_materials' to the MATLAB path. I think 'crystalline_materials' contains a set of sample crystalline materials which are used in the examples. Therefore, I am confused why is it necessary to add 'crystalline_materials' to the MATLAB path while compiling?

Pretty sure it is so that the examples can run.
Commands like Au001Crystal() are taken directly from the crystalline_materials.

Just out of curiosity, will not including these files impact the compilation of the code?

[thomasaarholt]

Only if they are called. I believe they should not be.

Yeah! This doesn't affect the compilation or the results.
